INNER BOOT FOR AUTOMOBILE TIRES.

To all whomit may concern:

Be it known that I, LEON G. BELOUD, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Inner- Boot for Automobile Tires, of jwhich the following is a specification. I I a My inventionrelatesto improvements in inner boots for tires in. which anumber of thin flexible strips of metal are disposed in a layer between sheets of fabric, said sheets of fabric being fastened together in such a manner, that each metal strip is separate-from all others, thus preventing contact between the individual metallic members of the layer in order that each individual strip of metal may be free tomove within a limited space independently from any other metallic strip contained in the boot.

I attain these objectsby the device illustrated in the accompanying drawing, in

. which Fig. 1 is a top view of the shoe, showing a portion of one of the sheets of fabric removed, in order to show the disposition of the flexible metallic strips.

Fig. 2, shows part of a section of tire, in which the shoe is applied to a damaged portion of the same illustrating the manner in which the metallic strips attach themselves to the carcass of the tire.

Similar letters refer to similar parts throughoutthe several views.

In Fig. 1 letters A and B indicate sheets of suitable fabric laid one on top ofv the other and permanently secured tog-ether by being stitched together with parallel. rows of A stitching which are designated in the drawing by the letters L, L, L, thus forming pockets wherein are placed the metallic strips 0, C, C. The two sheets of fabric are cut in an oblong shape, and placed across each other in such a manner that the longest side of one .shall lay at right angle to the narrowest portion of the other one. One of the strips of fabric, B is notched or gored as indicated by the letters, D, D, in order that the boot may easily conform itself to the curvature of the tire.

In Fig. 1 the sheet of fabric A is shown as being longer than the metallic strips, the purpose of this feature being to prevent any damage to the inner tube which might occur through contact with any of the metallic strips.

In Figs. 1 and 2 the metallic strips C, G, C, are bent as indicated by the letters E, E, E in such a manner that when under the IE'essure of an inflated inner tube, these nt portions E, E, E are securely driven into the body or carcass of the tire. The object of this construction is to enable the metallic strips'to freely respond to various fiexures and) to freely adapt themselves to the various shapes a tire assumes when in use, and at the same time to provide the means that will prevent the boot or strips of metal from shifting from the location desired.

In Fig. 2, F indicates a section of a portion of tire in which -H, shows an opening or tear over which are placed the metallic strip-s C, C, C, Whose bent ends are either shown as having been forced into the body of the tire or about to be, it being possible to show these in this manner by the removal of one of the sheets of fabric A, thus exposing the metal strips C, C, C, shown in the proper position on the other sheet of fabric, B.

As shown in Figs. 1 and 2 the bent portions of the metal strips E, E, E, are placed insuch a manner that portion E of each strip C lies alongside of the nnbent free end of the next nearest metallic strip, thus E E E appear alternately at the opposite ends of the fabric in such a manner that the end of each metal strip, which fastens said strip to the tire, is placed next to the free end of the strip which lies alongside and parallel thereto as indicated by letter A.

I am aware that prior to my invention boots for the protection of the tube, which are to be used in damaged tires have been made and used, therefore I do not claim such a combination broadly, but I claim:

1. The combination in a tire boot of layers of fabric with metal strips, interposed between the same, one end of each strip being free to move within said layers, all substantially as set forth. I

2. The combination in a tube protector of layers of fabric, fastened together in such a manner so as to allow the insertion of metal strips between them which can only move in one direction within said layers.

3. A blow-out boot for pneumatic tires comprising layers of fabric, fastened to gether in such a manner as to leave pockets, fastened together so as to leave suitable 10 each one of which is intended to contain a pockets in which are placed flexible metallic metallic strip, means secure each metallic strips which can fasten themselves to the strip at one end only, in order to allow play boot at one end only.

when flexed all substantlally set forth. LEON G- BEL OUD.

- 4. The combination in a tlre boot of layers of fabric suitably notched at the edge in Witnesses:

order that they will adapt themselves to the LYDIA TEAGLE, curve of the tire without wrinkling, and JOHN DEsMoND.
